<p>Using the <code>@Override</code> annotation is useful for two reasons :</p>
<ul>
  <li>It elicits a warning from the compiler if the annotated method doesn't actually override anything, as in the case of a misspelling.</li>
  <li>It improves the readability of the source code by making it obvious that methods are overridden.</li>
</ul>
<h2>Noncompliant Code Example</h2>
<pre>
class ParentClass {
  public boolean doSomething(){...}
}
class FirstChildClass extends ParentClass {
  public boolean doSomething(){...}  // Noncompliant
}
</pre>

<h2>Compliant Solution</h2>
<pre>
class ParentClass {
  public boolean doSomething(){...}
}
class FirstChildClass extends ParentClass {
  @Override
  public boolean doSomething(){...}  // Compliant
}
</pre>
